Application filed May 8, 1911. Serial No. 625,799.

T '0 all whom it may concern:

Be it known that I, WILLIAM H. BURT, a citizen of the United States,residing at \Vaterbury, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Shade-Holdersfor Incandescent Electric Lamps; and I do hereby declare the following,when taken in connection with the accompanying drawings and the lettersof reference marked thereon, to be a full, clear, and exact descriptionof the same, and which said drawings constitute part of thisspecification, and represent, in-

Figure 1 a side view partially in section of a shade holder constructedin accordance with my invention and shown as applied to the lower end ofan incandescent lamp socket. Fig. 2 a sectional view showing theclamping band of the socket in its open or extended position. Fig. 3 asectional view showing the clamping-band contracted.

This invention relates to an improvement in shade holders forincandescent electric lamps, and particularly to shade holders which areof cup-shape or which have a deep skirt so that the shade is supportedat some distance below the lower end of the lamp socket, the object ofthe invention being to provide means for attaching a shade holder ofthis type to the socket so that the shade will hang concentrically withthe light; and the invention consists in the construction hereinafterdescribed and particularly recited in the claim.

In carrying out my invention, I employ a shade-holder comprising a deepshell 2 and a collar 3. In the lower end of the shellshade-holdingscrews 4: are mounted in the usual way. Inclosed by the upper edge willbear against the surface of the socket 12 above the usual annular rib13. The outer ends 7 and 8 of the band are perforated to receive anadjusting screw 14 by which the ends of the band are drawn together soas to contract the band within the neck and clamp the same around thesocket. By forming the band with the lugs 11 the neck is locatedconcentrically with the end of the socket so that the shade isconcentric with the'bulb carried by the socket. The brass ringreinforces the upper end of the shell and forms a support for the upperedge of the band.

I claim A shade holder for incandescent lamps comprising a shell formedat its upper end with a collar having a notch in one side, a bandsecured to the inner face of said collar at points on opposite sides ofthe center of the collar opposite said notch, said band having endsprojecting outward through said notch, and means for drawing the saidends together, said band formed between its points of attachment withinwardly projecting shoulders.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
